MEANsFoR ELECTRIC-CURRENT DISTRIBUTION. 2

Application filed August 31, 1826, Serial No. 132,716, and in Australia October Ihis invention relates to means which are usable in connection with electric current distribution. The object, of the invention is to provide devices for electric current dis tribution which are interchangeable and which are readily assembled and disassembled. r H The invention comprises means consisting of a base of metal formed to receive a detachable metal cover and: devices adapted to be enclosed by such base and cover to which electric lead wires may be led. It. also comprises means whereby ccrtaincf the said devices are operatable for the purpose of controlling electric current. I

Said base and cover may be of any-suitable design or shape and within same is lo-.

cated an element constructed to receive at its head a cap piece designed toserve as a union connection for securing the cover to the base. Lateral flanges may extend from such element and one surface thereof may carry insulating material. The said element is provided with. an opening to receive there in electrical insulating components mounted for rotation in said element, portion or portions of such components carrying electric conductive contact means. Such insulating components are preferably made I in three separate parts.

On the elcmentmay be mounted in any preferred manner insulating blocks o'fapproved design carrying terminals. Com binations such as a one pole switch, double pole switch or a combined onepole switch andfuse may be arranged by suitably disposing desired blocks in association with the element whereby electric current may be controlled.

Leads wires can. be carriedto the means as sociated with the element through any suit; able devices associated with the base.

Referring to the accompanying drawings inivhich the invention is illustrated Fig. 1 is a pcrspectivcview of one form of the apparatus; Fig. 2 sectional plan thereof with cover removed; Figs. 3 and 4 sectional elevations on plane 3 3 and 4-4, 1; Fig.

U-shape with lateral foot flanges 8 adapted to be suitably secured. to a footplate 9 deattached to. the bottom of the bottom having a through ing ldtherein and the plate 9 also having an opening 11 thereinregistering with the opening 10. Electrical insulating material 12 is preferably provided for the interior of thecover 13 is also preferably provided for: theyouter surface of. the element 6;

In the side walls of the element 6; are openings to receive the components 14, 15, and 16 (Fig. 5.) which when assembled. (Fig. 6)

components are designed so that theymay be and disassembledfrom each other and also that they may be turned as a un-it when assembled together and disposed in the openings thereforinthc element 6. The component .15 is formed as a spigot to fit recesses in the components 14 and 16; the opposite ends ofthe component to octagonal or other suitable form to fit the corresponding recesses 17 and .18 in the respective components 14. and 16. Further, the ends 19 and 20 of the respectiveecomponents 14L and 16 are recessed to receive electric conductive plates 21 (Fig. or the electric and disc 24(Fig. 7) 22 as well as the plate 23 are in two pieces which pieces may be secured together by rivets .25. I

Through holes 26 are ponent 1 4;, and through vidcd in the component 16, while through holes 28 are provided in the component 15. Such through holes are intended to receive securing screws 29, the screws entering either conductive plate 23 and 22 I so i' 5 is screwed onto the through:

and the cover 2 isi screwed onto the cap 5. Said: cap 5 is ex-.

opens 2 and electrical insulating material vare carried in the said openings in the walls of the element 6 (Figs. 2 and 3) The'said:
